I think it’s also possible that some of us have more acidic skin oils than othersTrue. Often caused by diet, thus reversible. There are reasons bigger than fingerprints-on-records to lower your acidity: the body should be mildly alkaline for peak health.
But back to fingerprints-on-records — I have an old friend who says he’s an ’audiophile; sure has an audiophile system. But every time he handles a record, it’s with full thumb and two fingers, on both sides at once. And he has a great record collection! I keep telling him but he won’t change, drives me nuts to watch.
I put my thumb on the edge, and two fingers under the label. Nothing touches the grooves except the stylus.
